I need to get the transformation matrix from echelon form reduction over finite fields but I found in the documentation the following statement:
The matrix library used for Z/p-matrices does not return the transformation matrix, so the transformation option is ignored.
More specifically, the call:
M.echelon_form(transformation=True)
returns only the echelon matrix E but not the transformation matrix T, so that T*M=E, when M is over a finite field.
Is there any workaround? Can I get the transformation matrix over QQ and then reduce it over the finite field?
Any advice is much appreciated.
Thanks, Boyan
